If you want to use $broadcast you should use $rootScope.

$scope.startScanner = function() {

    $rootScope.$broadcast('scanner-started');
}

And then to receive, use the $scope of your controller:

$scope.$on('scanner-started', function(event, args) {

    // do what you want to do
});

https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$on
